Research And Optimization On The Communication Protocol Of The Internet Of Things Based On Wehealth

In the current health-monitoring system,wireless communication is playing a more and more important role. Especially for the widely used technology of the Internet of things in traditional medical monitoring equipment. Meanwhile, the concept of wireless electronic health (WeHealth) was born. Compared with the traditional medical monitoring methods, WeHealth brings the professional wireless real-time monitoring and treatment into reality. And from the aspects of services, security to the operation improvement, the combine of WeHealth and the technology of the Internet of things has brought in great changes to current medical industry. Short distance wireless communication protocol of Zigbee, as the main communication protocol in the Internet of things, has played a key role in the data transmission. Through the study and optimization of the protocol, this paper has achieved a reliable network communication protocol scheme based on WeHealth.First, this thesis studied the short distance wireless communication protocol of Zigbee and explored an appropriate protocol implementation scheme based on the specific application of WeHealth. Second, this thesis has given a proper design of the hardware and software of the communication protocol in the WeHealth system based on the special application of sudden disaster. And realized a WeHealth communication system and performed some tests on the system. According to the shortcomings exposed in the data transmission test, in the last chapter of this thesis, we put forward a variety of measures to optimize the communication protocol in order to meet the requirement of practical application better and have given some test results and simulation.Nowadays, the emerging concepts of WeHealth and the internet of things mentioned in this thesis has attracted the world wide attention. And on their further study and practical application, we can bring in many improvements in people’s life. The function of real-time monitoring of human physiological parameters in WeHealth also has very important significance for modern medical industry development...
